5.1 PRESETTING OF WHEEL DIMENSIONS

The balancing data is set by means of an “intelligent” automatic gauge; confi rmation of the measurement and the position appear on the display. The round part of the gauge must rest on the rim where the weight will be positioned.

The correct measurement is that which can be measured with the compass gauge provided.

on two correction planes inside the rim.

The balancing machine automatically interprets that the correction will be made with adhesive weights and the following appears:

While the gauge is moving the following appears: when the measurement has been stored:

For a different combination of the type or position of the weights on the rim, use the button .

AUTOMATIC WIDTH (OPTION)

At the end of automatic distance and diameter measurement, if the LA sonar is present, the machine prepares for acquisition of this value:

a) standard weights: when only one measurement is

made, the machine interprets the presence of a rim with clip-on weight correction

The LT script on the LH matrix display indicates that LIGHT

TRUCK wheel measurement is set (large dimension wheels such as off-road, trucks or wheels which protrude signifi cantly from the rim).

This function can be enabled/disenabled by pressing push

The width value (b) must be set with the buttons . button . Slowly close the wheel guard until a

“beep” is heard. If “AUTOMATIC START” is enabled when the guard is closed, the balancing machine performs a cycle to measure the imbalance, otherwise the width value just acquired is shown.

Choice with minimum static unbalance

This program is designed to improve the quality of balancing without any mental effort or loss of time by the operator. In fact by using the normal commercially available weights, with pitch of 5 in every 5 g, and by applying the two counterweights which a conventional wheel balancer rounds to the nearest value, there could be a residual static unbalance of up to 4 g. The damage of such approximation is emphasized by the fact that static unbalance is cause of most of disturbances on the vehicle. This new function, resident in the machine, automatically indicates the optimum entity of the weights to be applied by approximating them in an “intelligent” way according to their position in order to minimize residual static unbalance. c.

Obviously the P.P. measurement is normally greater than that of the 1st harmonic. Tyre manufacturers normally supply two different tolerances for the two eccentricities.

The radial eccentricity measurements is automatically carried out after the unbalance measurement without having to go into particular procedures. Remember to position the sonar sensor in front of the surface to be measured before pressing the button.

7. Diagnostics

7.1 INCONSISTENT

READINGS

In some cases, when a wheel that has just been balanced is repositioned on the balancer, the machine can detect an unbalance.

This is not a machine problem but is due to faulty mounting of the wheel on the flange. In other words, when mounting the wheel after initial balancing, it has taken another position with respect to the balancer shaft axis.

If the wheel has been mounted on the flange with screws, the screws may not have been tightened correctly (crisscross sequence) or the tolerances of the holes drilled in the wheel may be too large. Small errors, up to 10 grams

(0.4 oz), are to be considered normal in wheels locked with the relative cone: The error is normally greater for wheels locked with screws or studs.

If, after balancing, the wheel is still unbalanced when refitted on the vehicle, this could be due to an unbalanced brake drum or, very often, the tolerances of the holes drilled in the rim and drum are too large. In this case, balancing should be performed using a balancer with the wheel mounted on the vehicle.

The machine has a self-diagnostics cycle which identifies the most frequent malfunctions during the normal work cycle.

These malfunctions are processed by the system and shown on the display.
